Drinking Straws: A Pollution Estimate

Plastic straws have become a symbol of the global plastic pollution crisis. While they constitute a small fraction of plastic waste, they are a highly visible example of single-use plastics, which are used once and then discarded. Plastic straws are one of the top 10 most commonly found items in coastal cleanups globally, and an estimated 500 million straws are used daily in the US alone. Straws are also one of the most common types of litter on beaches, with one study estimating that 437 million to 8.3 billion plastic straws pollute the world's beaches. The ubiquity of plastic straws has made them a target of environmental campaigns, with cities, nations, and corporations proposing and implementing bans to curb their use.

Plastic straws are a small part of plastic waste

Plastic straws are a significant contributor to the world's plastic pollution. According to a 2018 article, Australian scientists Denise Hardesty and Chris Wilcox estimated that there are nearly 7.5 million plastic straws scattered along America's coastlines. This suggests that there could be between 437 million and 8.3 billion plastic straws polluting the world's beaches. Another study found that plastic straws were the third most common debris on an Indian beach, making up 9.3% of all macro-debris.

However, it is important to note that plastic straws are just a small part of the overall plastic waste problem. Straws comprise only 0.025% of the 8 million tons of plastic that enter our oceans annually. While they are a highly visible and concerning form of plastic pollution, with their presence in marine animals bringing the issue to the fore, they are a tiny fraction of the total plastic waste.

The focus on plastic straws has been criticised by some who argue that it takes attention away from broader discussions about waste management and the need to reduce all single-use plastics. Steve Russell, vice president of plastics for the American Chemistry Council, has stated that the emphasis on individual products like straws misses the point. Instead, he suggests that the key to tackling marine litter is investing in systems to capture land-based waste and convert used plastics into valuable products.

Despite the relatively small contribution of plastic straws to overall plastic waste, they have become a symbol of the issue of single-use plastics and their impact on the environment. They are an easy target for reduction or elimination, as most people can do without them, and their ubiquity makes them a significant source of pollution. The movement against plastic straws has been driven by public pressure and concern for marine life, with governments and corporations responding by considering bans or restrictions on their use.

While plastic straws may not be the biggest contributor to plastic waste, addressing their use is a tangible step towards reducing single-use plastics and a catalyst for broader change.

Plastic straw bans

Plastic straws have become a major focus of environmental campaigns in recent years. This is partly because, for most people, the straw is something that can be easily done without. Eliminating their usage rarely requires a drastic change in behaviour.

The plastic straw ban movement is gaining momentum worldwide, with bans being implemented in various locations, from individual cities to entire countries. In the United States, several states have banned single-use plastic straws, including California, Maine, New Jersey, New York, Oregon, Rhode Island, Vermont, and Washington. Other states such as Colorado, Illinois, and Indiana are also taking steps towards banning single-use plastic products, including straws.

In Europe, the European Union has taken measures to restrict the use of single-use plastics, including plastic straws, with signs displayed in establishments to communicate the policy to customers. The United Kingdom is also taking steps towards reducing plastic straw usage, with McDonald's testing paper straws in some locations and keeping all straws behind the counter.

While some argue that focusing on individual products like straws misses the point, environmental groups say plastic straw bans are an important step toward their ultimate goal of ending the circulation of single-use plastic. Plastic straws, being a symbol of a disposable lifestyle, have become a gateway issue for many people to understand the broader plastic pollution crisis.

Plastic straw alternatives

Plastic straws have become a major focus of environmental campaigns due to their contribution to plastic pollution. According to estimates, about 500 million straws are used daily in the US alone, with 8 million tons of plastic ending up in the ocean every year. While plastic straws offer convenience and protection for teeth health, their single-use nature and the lack of proper waste management have led to environmental concerns.

To address these issues, various alternatives to plastic straws have emerged, offering reusable and eco-friendly options:

• Metal Straws: Metal straws, typically made of stainless steel, are durable and reusable alternatives. They are easy to clean and suitable for hot and cold beverages. Some metal straws come with silicone tips for added comfort.
• Bamboo Straws: Bamboo straws are natural, biodegradable, and reusable. They are suitable for hot and cold drinks and often come with cleaning brushes and travel pouches.
• Glass Straws: Glass straws are easy to clean due to their transparency, and they conduct heat similarly to glass cups. They are a good alternative for those who prefer not to use metal straws.
• Silicone Straws: Silicone straws are flexible, easy to clean, and effective at stopping heat conduction. They are a good option for those seeking a reusable straw that is not metal or glass.
• Biodegradable Straws: Biodegradable straws made from plant-based materials such as wheat, sugarcane, or corn starch offer a compostable alternative. These straws are edible, although they may become mushy in hot drinks and contain allergens like gluten.
• Paper Straws: Paper straws are biodegradable and compostable, although they may not be as durable as other options and require disposal after one use.
• Pasta Straws: Pasta straws, such as those made by Stroodles, are flavourless, biodegradable, edible, and zero-waste. However, they may contain gluten, and their texture can be affected by hot drinks.
• Agave Straws: Agave straws are natural, sturdy, and biodegradable. They are thicker than plastic straws and provide a unique alternative to traditional straw materials.

These alternatives to plastic straws offer environmentally conscious options that reduce waste and pollution. By adopting reusable straws, individuals and businesses can contribute to a more sustainable future while still enjoying the convenience and functionality of straws.

Plastic straw usage estimates

Plastic straws are one of the top 10 most commonly found items in coastal cleanups worldwide. According to the Annual International Coastal Cleanup Reports 1988-2017, the US alone consumes 500 million plastic straws every day. This figure has been disputed, and the actual number could be less than half of that. Nevertheless, the amount spent on disposable drinking straws has been increasing year after year for the past two decades.

In 2018, Australian scientists Denise Hardesty and Chris Wilcox estimated that there are nearly 7.5 million plastic straws scattered along US shorelines, using data from cleanups over five years. They further calculated that this would mean that there are between 437 million and 8.3 billion plastic straws on coastlines worldwide. Another study published in 2015 estimated that 8 million tons of plastic enter the oceans annually, with straws accounting for just 0.025% of that.

A survey conducted along a beach on India's Gujarat coast in the Arabian Sea found that plastic straws made up 9% of the litter. Similarly, a preliminary study on a beach in India found plastic straws to be the third most common debris, accounting for 9.3% of all macro-debris. In Malaysia, an estimated 30 million straws were used daily, translating to one straw per person. In contrast, the United States had a higher per capita usage rate of approximately 1.6 straws per person per day.

The focus on plastic straws as a symbol of the fight against plastic pollution is interesting given that they constitute a relatively small proportion of plastic waste. For instance, of the 380 million tonnes of annual plastic waste, only about 23 million tonnes end up in the environment, with straws contributing a tiny fraction. The attention they receive may be due to the public perception that they are an unnecessary luxury, and banning them is an easy way to reduce plastic waste without significantly altering behaviour.

Plastic straw pollution solutions

Plastic straws are small and lightweight, making it easy for them to end up as litter. They are also non-recyclable, so they end up in landfills and incinerators, releasing harmful chemicals. Plastic straws can also harm marine life, such as seabirds, fish, sea turtles, manatees, and dolphins, and they are made from harmful materials such as polystyrene, which contains styrene, a likely human carcinogen.

To tackle the issue of plastic straw pollution, several solutions have been proposed and implemented worldwide. Some of the key solutions include:

Bans and Restrictions on Plastic Straws

Many cities and nations have implemented bans or restrictions on plastic straws to address the issue. For example, Seattle, Miami Beach, and the United Kingdom have considered or implemented bans on plastic straws, following the lead of other US cities. Hong Kong has also seen a significant drop in plastic straw consumption due to campaigns and restrictions. Banning plastic straws has become a global trend, with corporations like Starbucks, McDonald's, and IKEA joining the movement.

Straws Upon Request

Another approach is to offer straws only upon customer request. This strategy reduces the number of straws used and raises awareness about plastic pollution. McDonald's, for example, has adopted this approach, keeping straws behind the counter. "Skip the Straw" or "Straws Upon Request" laws are gaining popularity as a way to reduce plastic pollution and encourage the use of alternative options.

Alternative Materials and Reusable Straws

Businesses and individuals are encouraged to use alternative materials for straws, such as paper, bamboo, metal, or glass. These options are more environmentally friendly and can be easily recycled or reused. For example, Starbucks switched to paper straws and wooden stirrers in its branches across the globe. Reusable straws are also promoted as a more sustainable option for individuals who require or prefer using straws.

Waste Management and Infrastructure

Steve Russell, vice president of plastics for the American Chemistry Council, suggests that the key to solving marine litter is investing in waste management systems and infrastructure to convert used plastics into valuable products. This approach shifts the focus from banning specific products to addressing waste collection and recycling processes more broadly.

Education and Advocacy

Educating individuals about the environmental impact of plastic straws and encouraging them to refuse single-use plastics is essential. Initiatives like The Last Plastic Straw project aim to empower people to advocate for legislation to stop plastic pollution and spread the "plastic-free" message. Students are also encouraged to take action through film screenings, discussions, and projects that address single-use plastic pollution.
